Answer:

That is a cyclic quadrilateral. (A quadrilateral that is inscribed in a circle.)

In a cyclic quadrilateral, opposite angles sum to 180°

Therefore 3y + 8 + y = 180°

4y = 172

y = 43

Therefore angle R = 137

astraxan [27]

Answer:

y = x - 1

Step-by-step explanation:

Since the line is parallel to y = x + 5, it will have the same slope, which is 1.

Plug in the slope and the given point into y = mx + b, and solve for b:

y = mx + b

2 = 1(3) + b

2 = 3 + b

-1 = b

Then, plug in the slope and b into the equation:

y = mx + b

y = x - 1

So, the equation is y = x - 1

Find f(5) for f(x)=1/9(3)*O A. 27O B. 81O C. 9O D. 3

Vladimir79 [104]

$f(x)=\frac{1}{9}(3^x)$

If the function is asking what if x = 5, then we will substitute the exponent x with 5.

$f(5)=\frac{1}{9}(3^5)$

From the formula above, we will multiply 3 to itself five times (3 x 3 x 3 x 3 x 3) = 243

$f(5)=\frac{1}{9}(243)$

After that, we will multiple 243 to 1/9 or simply divide 243 by 9.

$f(5)=\frac{243}{9}=27$

Therefore, the value of the function if x = 5 is 27. Option A is the answer.
